Who has both nikon AND canon?

I'm a nikon shooter first and foremost. Have the D800e and most nikon glasses. I shoot mainly architectural shots and love the 14-24mm in most situations. However, one 'weakness' amongst the nikon lens lineup is the absence of the 17mm tilt shift lens that canon has. So when the opportunity arrived I bought the 5d3 along with the 24-105mm kit lens and the 17mm tse, justifying that the 5d3 is more of an everyday camera. So now i have have two systems. Anyone else have both canon and nikon? Would like to hear your story.
